While Queen Latifah was marrying all manner of couples at the Grammys on Sunday night, the Disney Channel slipped its own milestone under the radar: the first appearance of a lesbian couple on one of its TV shows.

It happened on the sitcom Good Luck Charlie (which is apparently written for the whole family, not just kids). Charlie has a playdate with a new friend, Taylor, who—it turns out—has two moms. As you can see from the clip above, that's treated as no big thing. The problem is, according to TV Guide's synopsis, "the potential new friendship is put to the test as one mom chats with Amy, and the other is stuck listening to Bob's dull stories."

"This particular storyline was developed under the consultancy of child development experts and community advisors," a Disney Channel spokesperson says. "Like all Disney Channel programming, it was developed to be relevant to kids and families around the world and to reflect themes of diversity and inclusiveness."

It's strange in this day and age to see lesbian parents treated as a little exotic. Plenty of kids (and probably plenty of kids watching the Disney Channel) are being raised by same-sex couples. Then again, I suppose you could read the little argument over Taylor's mom's name as a lesson in making assumptions.
